BOILER FIXING
FIRING RATE
TEST BOILERS
The firing rate has been defined through test boilers according to EN 676 standard.
COMMERCIAL BOILERS
The burner-boiler matching is assured if the boiler conforms to EN 303 and the combustion chamber
dimensions are similar to those shown in the diagram EN 676.
For applications where the commercial boiler does not conform to EN 303, or where the combus-
tion chamber is much smaller than the dimensions given in EN 676, please consult the manufac-
turers.
Separate the combustion head from the burner body
by removing the nut (1) and pulling back the group
(A)
.
Fix the group
(B)
to the boiler plate (2) inserting the
supplied insulating gasket (3).
